Chemical Recycling Technology of Polylactic Acid/talc—Application into Agricultural Materials—
Open accessAbstract
バイオマス率の向上とリサイクルシステムの導入の可能性について，バイオベースポリマーを農業機械部品として利用した後，ケミカルリサイクルによって資源循環させることを検討した．バイオマスの根幹である農業分野の機械に使用されるギヤグリップにポリL-乳酸(PLLA)を主体とする材料を用いた．具体的には，農業機械の使用後のPLLAギヤグリップから熱分解によって選択的にラクチドモノマーを連続回収する．回収したL,L-ラクチドは押出成形機内で再重合，射出成形機にて育苗ポットを作製した．引張強度は54.4 MPaとバージン材と同等であった．育苗ポットに植物を育成し，生長に問題ないことを確認した．

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
